Guaranteed, made certain (7)
I believe the answer is:
ensured
I believe this is a double definition.
'guaranteed' is the first definition.
('ensure' can be a synonym of 'guarantee')
'made certain' is the second definition.
('ensure' can be a synonym of 'make certain')
(Other definitions for ensured that I've seen before include "Saw to it" , "Make certain of" , "Made certain for end user" , "Determined" , "Made certain, clinched" .)
